Chemraz ORings

Chemraz® O-Rings : Perfluoroelastomer : Fluorocarbon Rubber

Green, Tweed's Chemraz has the broadest chemical resistance of any elastomeric material, combining the resilience and sealing force of an elastomer with chemical resistance approaching that of PTFE. Chemraz O-rings, gaskets, and custom elastomeric shapes extend MTBR (mean time between replacement) in harsh environments and withstand a wide range of temperatures (-20°F to 615°F, -30°C to 324°C).

Chemraz's distinctive chemical composition makes it well suited for a wide range of applications. Because of its low compression set, outstanding physical properties and universal chemical resistance, Chemraz provides an incredibly high sealing force.

A field-proven, universal compound having the broadest range of chemical resistance on the market. Chemraz 505 is ideal for processes taking place in subzero temperatures as well as for use in multi-substance plants or in mixed media.

Greene Tweed’s Chemraz® 510, a perfluoroelastomer, offers an extremely broad range of chemical resistance with a Shore A hardness value of 90. with a temperature range form -22°F to 446°F (-30°C to 230°C), Chemraz 510 is well suited for use in a range of applications, from mechanical seals to pump housings.

This specialty black compound was formulated for incredible resistance to rapid gas decompression (otherwise known as explosive decompression) damage common in high pressure gas services. Chemraz 526 is also used in monomer services where polymerization attacks and ruptures common elastomeric seals.

Chemraz 551 is ideally suited as a universal sealing material for aqueous semiconductor wafer processing and chemical/DI water distribution systems. It's the elastomer of choice for the most demanding applications from Ozonated DI water to Hot Sulfuric Resist Strip.

Chemraz 555 provides a significantly wider operational band and superior compression set resistance than any other broad range perfluoroelastomer on the market. With an upper temperature limit of 600°F (316°C), it is the elastomer of choice for the most demanding services found in the chemical process and refining industries.

These specialty cream Chemraz compounds are formulated to withstand the most demanding chemical process applications. Chemraz 584 is a good elastomer for strong oxidation fluids and hot aqueous solutions.
